New Caledonian Crested Gecko, Rhacodactylus ciliatus, also called Guichenot's Giant Gecko or Eyelash Gecko. The nocturnal gecko's vertical pupils open wide in dim light, closing to narrow slits in a fraction of a second when exposed to bright light. Endemic to New Caledonia in the South Pacific, the crested gecko was thought extinct until it was rediscovered in 1994. It is now one of the most commonly kept species of gecko in captivity. .
